Abstract

543,055. Silencing gaseous currents. BLANCHARD, J. G. July 4, 1940, No. 11258. [Class 7 (ii)] A silencer, particularly for the intakes of engines, compressors &c. comprises inlet tubes 2 passing through a casing 1 and connected to a transverse tube 4 which projects through the side of the casing for connection to the engine &c. an intermediate tube 5 being arranged eccentrically within the casing so as to form substantially crescent-shaped chambers 6 and 7, the former of which is open to the inner end of the tube 4, and the latter is connected to the tube 4 by apertures 8. The chambers are dimensioned according to the frequencies of the noises to be silenced, and are evacuated by the suction of the intake gases. The casing may be lined with felt or other sound-absorbent 9, and filters 11, 12 may be provided at the open ends of the tubes 2. The chamber 7 may be divided by partitions 15 fitted with connecting-tubes 16. More than one intermediate tube may be provided to form more than two crescent chambers.
